New asphalt can usually handle light traffic within a day or two, but it stays soft for months. After asphalt driveway paving, we ask homeowners to keep feet and tires off the surface for 24 to 48 hours.
As Wayland, MI asphalt paving contractors, we hear this question on almost every job.
Here's what to keep in mind before you pull onto fresh blacktop.
Curing and Hardening Run on Two Clocks
Hot-mix asphalt goes down hot and has to cool before anything rolls over it. One state road spec keeps traffic off a common mix until its .
Cooling takes hours. Hardening takes much longer, because the binder slowly stiffens through .
That's why full curing can take several months, even though the surface feels solid by the next morning.
New Residential Driveways
Passenger cars are usually fine after the first two days. Until the asphalt firms up, though, it can still dent and scuff.
Some city guides are even more cautious. Golden Valley, Minnesota, tells residents to wait a week before driving and warns that parked vehicles can .
New Commercial Parking Lots
A newly paved lot should stay closed to foot and vehicle traffic for at least 24 hours. Garbage trucks, delivery vans and other heavy loads need more patience than customer cars.
Our parking lot paving crews can often work in stages so part of the lot stays open. These tips on closing your lot for paving help you plan around the wait.
Weather and Temperature Change the Timeline
Hot, sunny days keep fresh asphalt soft longer. Highway agencies surveyed in an Oklahoma study ranked layer thickness and wind speed as the biggest factors in .
Summer heat can soften even older pavement, as we cover in how hot weather affects parking lots. Fall paving cools faster, but it still needs dry ground and temperatures above 50 degrees.
Once the ground freezes, the West Michigan paving season is done until spring.
What Damages Fresh Asphalt in the First Months
Most early damage comes from weight that stays in one place or tires that twist on the surface. Watch out for:
- Turning the steering wheel while the car is stopped
- Parking in the exact same spot every day
- Trailers, campers, dumpsters and heavy equipment
- Kickstands, jack stands and ladder feet on hot afternoons
- Gas, oil and other petroleum drips
Fluids deserve extra attention. Researchers found the solvent action of hydrocarbon spills can and loosen the stone it holds.
Simple Habits That Help New Pavement Last
Rotate where you park and keep heavy loads near the edges off limits for the first season. Put a piece of plywood under anything with a small footprint that has to sit on the asphalt.
Sweep off debris and rinse away spills as soon as you see them. A little care now pays off for the next 20 to 30 years.
Frequently Asked Questions
Why does my new driveway have scuff marks and small dents?
Some scuffing and shallow dents are normal because fresh asphalt stays tender for several months. Turning the wheel while the car is parked and stopping in the same spot every day cause most of them.
Golden Valley, Minnesota, notes in its driveway guidance that some depressions are expected and suggests parking in the garage while the pavement cures.
Will gas or oil drips hurt a fresh driveway?
Yes, petroleum drips can soften and loosen fresh asphalt. Gasoline, motor oil and solvents share a chemical base with the asphalt binder, so a leak can weaken the surface where it pools.
Soak up spills quickly with an absorbent and park a leaking vehicle somewhere else until it's repaired.
Can A-1 Asphalt keep part of my parking lot open during paving?
Often, yes. On larger lots with more than one entrance, our crew can pave in stages so customers, tenants or employees keep parking in one area while another section is closed.
Each section reopens once it's ready for traffic. We'll let you know in advance when each area is ready for foot and car traffic.
Is it too late to pave a driveway in West Michigan this fall?
Not always. A-1 Asphalt can usually pave from April to October, as long as the ground is dry and not frozen and the temperature stays above 50 degrees.
Hot-mix asphalt has to stay hot to compact well, so a cold snap can push a project to spring. Call A-1 Asphalt at (616) 877-4400 to see what fits this season.
Does a thick commercial lot take longer to open than a driveway?
It can. Thicker asphalt holds heat longer and calm air slows cooling, so heavy-duty commercial pavement may need more time before traffic than a thinner residential driveway.
An Oklahoma DOT study for the Federal Highway Administration found highway agencies ranked layer thickness and wind speed as the biggest factors in how fast new asphalt cools.
